To all whom it ymay concern.:

Be it known that I, CHARLES H. Si-isranu, citizen of the United States, and resident of the borough of Brooklyn, cit of New York, in the county of Kings an( State of New York, have invent-ed cert-ain new and useful Improvements in Type-VVriting Machines, of which the following is a specification.

In some typewriting machines heretofore constructed it often occurs that a type bar or carrier will return to the normal position with such force, es ecially when the machine is rapidi opera ed, that the carrier will reboun from the normal position, and should the operator depress the key of an adjacent type ar or carrier while this rebound is takin' place, the rebounding b ar will interfere with the subsequently operated bar in its movement to the printing oint. This defect is especially inherent in iiioiit strike typo writing machines wherein the type liars are mounted in a segment and wherein it is necessary to mount t-lie type bars in close and compact arranvciiieiit, in order to provide a sulllcient number of bars iii the machine. The arrangement is often such that a bare clearance is provided for each liar in the movement Athereof to the printing point and past the adjacent bars. .It will be readily understood therefore that unless each liar is in its normal position when the adjacent bar is operated, the previously o erated baris apt to he in the lpath of the su isequently op erated bar and interfere with its movement. Of course, the faster the machine is operated the more pronounced will be this dcfectf One ob]ect of my present invention is to overcome this defect iii existing t pewriting machines and'to provide a siiiip e and effi 'cient structure wherein it is impossible for the typo carriers to rebound to an interfering cxtent,

A further object of my invention is to provide a simple, efficient, quick and easy., ty c bar action and one wherein a comparative y slight movement is ini arted to the type bar or carrier during the first portion of the key de ression and in which this movement is ac ce erated as the bar ap roaches the platen during the last part 'of t e key depression.

To these ends my invention consists in the novel `features of construction and arrangements and combinations of parts hereinafter actuating link pivoted at described and particularly pointed out` in the i claims.

In the accompanying drawings wherein like characters represent'corresponding parts iii the various views zFigure 1 is a vertical A sectional view of sufficient number of parts v of a typewriting machine to illustrate my ir'ivention, the section beingtaken from front to rear of the machine. 141g. 2 is a diagrammatic side view of the action. Fig. 3 is a like view of the same, the parts heilig illustrated in the positions they assume when the type bar is at the printing point.

1 is the framework of the machine, 2 the tog plate, and 3 a type har segment in the rat iating slots 3 of which are mounted the type b'ars or type carriers 4, the pivot rod of said type bars eilig indicated at 5. 6 is an 7 to the type bar 4 and tiie opposite end of to an actuating lever b at the point marked 9. 10 is a horizontal key lever to which the actuatin" lever S is pivot-ed at 11,v and the lower end o nach of the actuating leve-rs S. is pivoted atan iinvaryiiig point as at 12 to one end of a guide link 13 that is pivoted to a fixed portion of the machine at 14. When I refer to the actuating lovers S and guide links 13 as beinr connected at unvarying points 12 I means that there is no variation in these points of connection during the operation of the machine.

To the rear of the segnientally arranged type bars and their actuating mechanism, is a rixed segmental locking bar or abutment l5, which is secured to the top plate 2 of the machine as indicated at 16. Each of the levers 1() is provided with a finger key 17 and is ivoted at its rear end at 1 8, and is proviiled with a suitable spring 10X that tends to restore each key lever and its cooperating arts to their normal positions. Extending beneath the key levers is a universal bar 19 Iwhich is connected to upwardly extending links 20 that are united at 21 to a bar 22, which is carried by an arm 23 pro'ecting lrom a rock shaft 24 of the. dov roc er 25. lhe dog rocker 25 may be provided with the usual feed dogs 26 that are adapted to cooperate with any suitable cooperating feed rack 27; carried by a suitable platen carria e, not shown.

-rom an examination of Fig. 1 of the this link is pivoted` bar or abutment, thus preventin any reare m the normal position so that there can tween the full line and dotted line position a.

the parts back to the normal position will l will elek@ the locking abutment in this ack- `they aremoved *they follow a different-path of movement at the initial key from the drawinfit will be-seen that a utf'a twothirdsV epression of a key is reurred to,

drawings, it will be observed that the rear end of each actuating link 6 is directly forward of the lockingubar or abutment 15, and is maintained in t 's position when its key lever is in the normalposition and lthe slightest rebounding movement of a t e bar from the normal osition, indicateci'iiy the lowermost bar in gig.' 1, will force the link or the lever 8 towhich it is connected, or both back into contact with said locking bounding movement of the type ar which would permit it to extend into the path of an adjacent type bar. A depression however, of any of the key levers will cause its associated link 6 firstto be moved down suciently far to enable it to clear thelocking abutment, as indicated at Fig. 2 of the drawings, wherein the amount of depression of the key is indicated by` the difference be- The course of travel of the pivot 9 which unites the actuating lever and its link, is indicated in dotted lines in Fig. 3, which represents the type bar in the printing positlon. It will be understood that the movement'of cause the actuating link vor the lever at the point of its connection. with the link, to traverse this same path, so that the arts Ward movement. From the foregoing descriptiom it will be 'seen that the actuatin link and lever of each action have one Ipat o i movement when y a key lever,' whereas,l

during the very slight rebound of a type bar.A and until they reach contact with the locki bar. In practice the actuating lever and liit may be brou ht into actual .contactwith the locking autr'nent when the parts be norebound movement Whatever of the parts. Notwithstanding the fact that the various portions of each action are positivel connected, a slight movement of each key ver and its connected parts 'tkes place portion of the depression of au key lever wit out transmitting motion4 to the t bar. The lost motion thus'produce 1s due to the peculiar disposition of the parts of each action, and is indicated' byA the dotted lineposition c of the foremost nger key in-Figi 1. A movement of each fu .line position to the posi-l tion indicated atc takes 'place'before anymovement is transmitted to the type bar.

From an examination of F' 1, of the rien' more thetyps'h from its fwprint-..1

w abQutonhuf the distan tothe' ing point. This is clerlyindicmd 'pivot .14, thereby causlng t movement of the .type bar just beforean at b a` ...madam-of shdoedwiiae a in 1, which corresponds to the normal position of the key, wit the full line -position of the same key. B com aring this dotted line position a with t e ful line osition ofthe same key, it will be seen that t e key has traveled about two-thirds of the distance between the initial position and the limit of this movement which is indicated in dotted lines at b. It will likewise be seen that it only requires a further depression of this key from the full line position to the dotted line .position b to move'the coperating type bar one-hall the extent of its travel.

In operation, a slight'lost motion is produced at the initial portion of the key depression which is followed by a slight movement of the. type bar through the first portion ofthe depression of the key lever, whereas an accelerated or morerapic movement of the type bar is produced as the type bar approaches the printing Upoint.- For this reason an easy and quick action is provided.

While I have shown the various features of my invention as embodied in a front strike tyewriting machine, it should be understoo that they may beemployed in other styles of writing machines.

It will be seen that the actuating lever 8 extends across itsassociated key lever 10 Vand the point of connection 12 between each lever 8 land its guide link'13 moves in a fixed l or unvarying a'rc around the pivot 14. It

will likewise be seen that the lever 8 is supported on 4the swinging fulcra 11 and' 12, which move in opposite arcs, the link 13 extendin from its pivot in a 'direction opposite that 0F the key lever 1() from its pivot. The link 13 extends forwardl from the lever 8, said link standing norma ly crosswise of and approximately at rightV angles vto a line connecting the ends 9 and 12 of the sub-lever,4

andthe lower end of lever 8 is farthest from the fixed center 14 considered fore and aft of the machine when the partip 'mal position but when a are in the norn er key is depressed the lower end of the ever 8 will be rought nearer to the fixed point 14. At the first part of `the ke depression, the lever 8- will vibrate slowly4 utas the t e bar continues its movement towards t c printing point, the lower end of the lever 8'will be swung with greater rapidity4 l e most ra id the 4timeitreachesl the printing position. On the return movement of the type bar it V travels with the greatest s eed near tlie` printing point, 1n order quie y to clear the path o other bars 1n their approach to theplaten, and then gradually slac ensits speed as-.it approaches .the normal position. By sting heisses as shawn and described the lower en of the lever 8 is drawn forwar by an easy action' ofthe parts., dur.- ingthe depression o f akey lever, andthe upabutment againstAWhich a part of the intermediate actuating means is adaited to abut when a carrier rebounds from t ie noi- `mal osition, the path of movement followed by t e said part of the actuating niean's during the rebound of its carrier being different from its path of movement when operated by its key lever.
